Proof. Using the conditions on pp [Ebe21, Theorem 1.1] shows that the motive M⁡(μ−1​({x}))\operatorname{M}(\mu^{-1}(\{x\})) of a Springer fiber is pure Tate which implies (PT). Moreover, there are only finitely many GG-orbits in 𝒩n​i​l,\mathcal{N}_{nil}, see [Car93], which shows that condition (FO) holds. ∎
